- the weights can be partially hoffowed out while still retaining the same essential profile so as to be retained by the ledges 23a, 23b. In this way, the large weight of Figure 1 , for example, could be reduced in mass, while still maintaining the same effective occupancy area in the weight region 20a.
- the swimfeeder body has a number of advantageous structural features.
- the outer shape of the swimfeeder is smooth, relatively streamlined and the specific geometry and dimensions carefully chosen experimentally to give a good performance in casting, retrieving and holding the bottom in a current. Because the compartment 35 is located within the body 20, the carefully designed outer shape does not change with loading and so can be cast in a predictable way which facilitates casting accuracy. It will be appreciated that a swimfeeder which oscillates or behaves erratically on the retrieve can cause variability in the line lay on the reel spool which, thereafter, adversely affects casting accuracy. Since the weights are held in the compartment 35 in a way which inhibits lateral movement, the lateral stability of the swimfeeder during casting assists with casting accuracy.
- the centre of gravity of the swimfeeder remains on the same central longitudinal axis independent of whether a single weight or a combination of 2 or more weights from the set is or are loaded in the compartment 35, consistency in casting is facilitated. It is thought that it is also advantageous to locate the holes 32,32a such that they do not extend into the compartment 35 again to help make the streamlining of the swimfeeder independent of the loading.
- the hole 32a is located such that if a weight becomes jammed in position because of groundbait debris or the like, the weight can be dislodged and pushed towards the open end 22 of the body 20 by inserting an angler's disgorger through the hole 32a.

Abstract
Description
- The present invention relates to the field of swimfeeders.
- A swimfeeder is a device used in fresh water angling that is attached to a fishing line near to the hook and which holds bait for attracting fish to the hook. The swimfeeder is adapted to be cast and to sit on the river or lake bed. A variety of types of bait may be used with the swimfeeder, including particulate bait such as maggots, seeds etc, and ground bait.
- In river or lake fishing with a feeder, a bite is normally indicated by a quiver tip at the end of the rod. It is a distinct advantage for an angler to be able to adjust the weight of the swimfeeder such that it sits on the river bed while the quiver tip retains useful sensitivity as a bite indicator.
- Traditionally, adjustment to the weight of the swimfeeder has typically been carried out by affixing extra lead in the form of shot, strips and the like to the body of the swimfeeder to supplement the weight already present at its nose or base. One solution involves the use of small lead weights with thin tab/legs which are bent to grip the body of the swimfeeder.
- Once at the waterside, even an experienced angler can judge only roughly the amount of weight required for a given size of swimfeeder in order for it to behave correctly. These approaches have proved to be rather inconvenient in the messy conditions encountered at the waterside.
- Thus, the common practice has developed in which the angler pre-loads a considerable range of swimfeeders with a variety of different weights and transports all those swimfeeders to his swim, or to the peg he has drawn in a fishing match. If the weight he estimates is not quite right, the popular approach is for him to remove the whole feeder from the terminal tackle and replace it with a different one.

FR2650155 - With the foregoing in mind, according to an aspect of the Invention, the present invention may provide a swimfeeder kit comprising a swimfeeder having an elongate body having an open end and defining a region for weights and a region for balt, a cap for closing the open end and a set of weights, wherein more than one of the said weights may be loaded, at the selection of the angler, into the weight region via the open end and occupy the weight region at the same time, characterised in that the centre of gravity of the weights in the weight region is kept on the same longitudinal axis of the body independent of the number of weights loaded in the weight region.
- A swimfeeder kit in accordance with the present invention enables the angler to load one of said weights into the weight region, or as needed more than one of said weights Into the weight region so that they occupy it at the same time, whereby, depending on the selection of weights from the set, the angler is able to adjust the overall mass loaded into the swimfeeder to match his estimate of that required by current river conditions. Should that estimate prove to be incorrect or the fishing conditions change, the weight region of the body can be loaded with different combinations of weights selected from the set, preferably, without needing to remove the swimfeeder from the line.
- The number of combinations of possible loading depends on the number of weights which can be accommodated by the weight region of the body at the same time, the number of weights in the set, and their mass ratio.
- Preferably, each weight in the set has a different mass. By virtue of each weight having a different mass, the number of possible loadings which can be applied to the swimfeeder is maximised for a given number of weights in the set. In other embodiments, some or all of the weights may have the same mass.
- Preferably, the set comprises at least one weight made from a first material having a first density, and at least one weight made from a second material having a second density, wherein the first and second density are different. By virtue of the set consisting of weights of different density, for a weight region of a given volume, the range of loadings which may be applied to the swimfeeder can be widened. A preferred choice of materials is mazak or zamak and lead, the latter material having a distinctly higher density than the former materials.
- Preferably, the weight region is located at the bottom of the body, the weights comprise slabs, and the weight region is adapted such that slabs in the weight region are held In minor face-to-minor face orientation. By confining the slabs to the bottom of the body in a minor face-to-minor face orientation, the necessary bottom weighting of the swimfeeder body can be achieved while leaving a good continuous volume of bait region in relation to the overall size of the swimfeeder body. When in minor face-to-minor orientation, minor faces of the slabs may be In contact with one other. In other embodiments, structures within the weight region may keep them apart.
- Preferably, the body comprises a plurality of through-holes for bait, wherein the through-holes open onto the balt region and not onto the weight region. In this way, the external profile of the swimfeeder body is independent of the load.
- Preferably, the body is elongate, and the weight region is adapted such that weights In the weight region are confined so as to prevent their lateral movement.
- By so confining the weights, the centre of gravity of the weights is kept on the same longitudinal axis during casting, thereby assisting with casting accuracy. In a preferred embodiment, the weights in the weight region are held by the body in an interference fit.
- Preferably, the body is elongate, and the centre of gravity of the weights in the weight region is kept on the same longitudinal axis of the body independent of the number of weights loaded in the weight region. By virtue of the centre of gravity of the weights in the weight region being on the same longitudinal axis independent of the number weights in the weight region, the lateral stability of the swimfeeder during casting is load independent which assists the angler in achieving consistency in casting. Preferably, said longitudinal axis is the central longitudinal axis of the body.
- Preferably, the weight region comprises a single compartment defined between a base, a wall upstanding from the base and a formation projecting inwardly from said wall. In other embodiments, the weight region may comprise a plurality of adjacent compartments.
- Preferably, the slabs are of identical cross-section, and a first group of the slabs has a first length, and a second group of slabs has a second length, wherein a combination of at least one slab taken from the first group and at least one slab taken from the second group fills the weight region to capacity. In a preferred embodiment, a single first group slab and a single second group slab fill the weight region to capacity. An advantage of filling the single compartment exactly to capacity is that longitudinal motion of the weights is inhibited.
- According to a further aspect of the invention, the present invention may provide a swimfeeder suitable for the swimfeeder kit as described above.
- According to a further aspect of the invention, the present invention may provide a set of weights suitable for the swimfeeder kit as described above.
- According to a further aspect of the invention, the present invention may provide the use of the swimfeeder kit as described above by selecting one or more of said weights from said set and loading the selected weights into the weight region.
- The provision of a compartment within the swimfeeder Into which weights can be inserted is advantageous in that it enables the swimfeeder to be loaded in a positive and non-flddly manner which is desirable on the waterside. Also, by filling the compartment to a greater or lesser degree with a suitable combination of discrete weights, the total loading applied to the swimfeeder can be easily varied.
- Exemplary embodiments of invention are hereinafter described with reference to the accompanying drawings, in which:
-
Figure 1 shows an embodiment of a swimfeeder in accordance with the Invention with parts removed and just prior to loading with weights; -
Figure 2 shows the swimfeeder ofFigure 1 after loading with two discrete weights; -
Figure 3 shows swimfeeders similar to that InFigure 2 in a range of sizes and In side, end and perspective views; and -
Figure 4 shows side, end and perspective views of another embodiment of a swimfeeder in accordance with the Invention which is loaded with three discrete weights. - A swimfeeder kit for fresh water angling In accordance with a preferred embodiment of the invention comprises a swimfeeder and a set of discrete weights. The swimfeeder is designated 10 and, as shown in
Figure 1 , comprises an elongate hollow body 20, made from polymeric material, which is adapted for casting and to sit on the lake or river bed. The body 20 has a central longitudinal axis A-A and is generally of a 'D'-shape in cross-section, with the wall corresponding to the straight back of the 'D' serving as a base wall which is designated 21a, and the curved portion of the 'D' corresponding to the curved wall designated 21b. The body 20 has anopen end 22 and a closedend 24. As shown inFigure 2 , theopen end 22 is closed off by acap 26 which is held in place by an elastomeric cord orfilament 28 which extends from ananchor 30 on the closedend 24 along the longitudinal axis A-A through thecap 26 to aloop connector 31 which it holds in position on thecap 26. The loop connector is the means by which theswimfeeder 10 is attached to the terminal tackle. - The properties of the
cord 28 are selected such that during casting and whilst, in situ, on the lake or river bed, thecap 26 is held firmly in place, but also such that there is sufficient elasticity in it to allow the angler to dislodge the cap and hold it off to one side, thereby allowing bait or weights entry into the body 20 as hereinafter described. The body 20 also comprises a plurality of through-holes communicating between the interior and exterior of the body 20 to allow bait contained in the body to escape once theswimfeeder 10 has been cast into the lake or river. The through-holes are labelled 32 except for the one closest to thebase 21a on the closedend 24 which is labelled 32a. - The body 20 also includes formations in the form of
ledges curved wall 21b at a small distance above and parallel to thebase wall 21a and protrude inwardly a short distance into the body 20.Abutments 25 are also formed on the inside of theclosed end 24 at a level close to thebase wall 21a. The region orchamber 20a between the base wall 21, theledges abutments 25 is the region into which the weights are intended to be loaded. It may be seen that the weight region 10a extends across the full width of the body 20 and is centred on the central longitudinal axis A-A. In this embodiment, it comprises a single compartment 35. The region orcavity 20b between theledges abutment 25, thecurved wall 21b is the region into which bait is to be deposited. In other embodiments (not shown), theledges base 21a does not extend continuously across the bottom of the body and, in one embodiment, extends only partway, for example, in a manner similar to theledges base 21a , rather than immediately adjacent to thebase 21a as in the illustrated embodiment. - In this embodiment of the invention, the set of weights comprises four weights per set: two equally-sized large weights, one made from the alloy mazak (density/specific gravity = 6.7) and the other made from lead (density/specific gravity = 11.0), and two equally sized small weights, again one made from mazak and the other made from lead. In
Figure 1 , a large 20g mazakweight 40 and a small 10g mazakweight 42 are shown in a position ready to enter the compartment 35. Each weight is in the form of a slab comprising acentral portion 45 having a pair oflateral wing portions 47 which are of a depth slightly less than thecentral portion 45 such that the top surface of the central portion stands slightly proud of the top surface of the wing portions. Each weight comprises minor faces 48. The cross-sectional dimensions of the weights are the same and selected so as to facilitate insertion into the compartment 35 and snugly entrain thewing portions 47 between theledges Figure 2 . The entrainment of thewing portions 47 means that any slab in the compartment 35 will be held in the same fixed orientation, whereby adjacent slabs will necessarily be held in minor face-to-minor face orientation. Also, lateral movement across the body, that is in a direction parallel to the axis B-B, is also inhibited by the entrainment. - Further, the overall combined length of the
large weights 40 and thesmall weight 42 is designed to ensure that when the cap is in the closed position the weights are snugly captured in contact with theabutments 25 and thecap 26. By selecting the dimensions in this way, the weights are firmly held in the compartment 35 and eliminating any possibility of longitudinal movement in the body 20 during casting. When the angler chooses to load the body 20 with only one weight and theweight region 20a is thus only partially filled, the interference fit between the weight and the body tends to retain the weight at the position in theweight region 20a which the angler sets. Normally, the angler pushes the weight all the way to theclosed end 24 of the body 20 such that it sits in engagement with theabutments 25 which is better for casting Although the interference fit holds the weight in position, theclosed end 24 of the body 20 is a particularly secure position for the weight since the relatively large forces encountered in casting tend to act in a direction which would urge the weight towards theabutments 25. - Thus, to reach the
Figure 2 loaded condition, the angler must hold thecap 26 off to one side and slot theweights cap 26 released and allowed to return to its closed position. - By selection of a single weight or a combination of 2 weights from the set, a range of possible loadings for the swimfeeder is generated.
- It is pointed out that the swimfeeder featured in
Figures 1 and2 is a large size swimfeeder.Figure 3 shows further smaller scale versions of theFigure 1 and2 embodiment, namely medium, small and mini versions which use lighter weights, but otherwise are constructed and operate in the same way. - Table 1 shown below illustrates how for a swimfeeder of a given size, and using a set of 4 weights with various parameters, a range of loading for the swimfeeder is made possible. The "large" row corresponds to the swimfeeder featured in
Figures 1 and2 .Table 1 SMALL MAZAK LARGE MAZAK BOTH MAZAK SMALL LEAD LARGE LEAD BOTH LEAD S MAZAK S LEAD L MAZAK S LEAD S MAZAK L LEAD LARGE 10g 20g 30g 16g 34g 50g 26g 36g 44g MEDIUM 8g 16g 24g 14g 26g 40g 22g 30g 34g SMALL 6g 12g 18g 10g 20g 30g 16g 22g 26g MINI 4g 8g 12g 7g 13g 20g 11g 15g 17g - Table 2 summarises the range of possible weight loadings. It will be noted that relatively small weight increments can be achieved over a wide range of loadings for a given size of swimfeeder.
Table 2 LARGE MEDIUM SMALL MINI 10g 8g 6g 4g 16g 14g 10g 7g 20g 16g 12g 8g 26g 22g 16g 11g 30g 24g 18g 12g 34g 26g 20g 13g 36g 30g 22g 15g 44g 34g 26g 17g 50g 40g 30g 20g - In
Figure 4 , another embodiment of the invention is shown. In this embodiment, the swimfeeder kit comprises a swimfeeder having a different arrangement ofholes 32, and a set of 6 weights. Theweights 50 are equally sized but comprise two different materials, again a lead weight and a mazak weight. For three different possible sizes of swimfeeder, the possible weight loadings using various combinations of weights from the set are shown.Table 3 1 MAZAK 2 MAZAK 3 MAZAK 1 LEAD 2 LEAD 3 LEAD 1 MAZAK 1 LEAD 2 MAZAK 1 LEAD 1 MAZAK 2 LEAD LARGE 10g 20g 30g 16.5g 33g 49.5g 26.5g 36.5g 43g MEDIUM 8g 16g 24g 13.15g 26.3g 39.45g 21.15g 29.15g 34.3g SMALL 6g 12g 18g 9.75g 19.5g 29.25g 15.75g 21.75g 25.5g - Thus, it will be appreciated that an above-described swimfeeder kit provides the angler with a swimfeeder which may be conveniently loaded with a range of weights even in the messy conditions at the waterside without detaching the swimfeeder from the terminal tackle. Advantageously, the weights are constructed out of materials and made to a size which creates many permutations of possible total loading for the swimfeeder, whereby a considerable degree of fine tuning of the total loading can easily be achieved. As an additional or alternative way of creating different loading permutations, the weights can be partially hoffowed out while still retaining the same essential profile so as to be retained by the
ledges Figure 1 , for example, could be reduced in mass, while still maintaining the same effective occupancy area in theweight region 20a. - It will be appreciated that the swimfeeder body has a number of advantageous structural features.
- The outer shape of the swimfeeder is smooth, relatively streamlined and the specific geometry and dimensions carefully chosen experimentally to give a good performance in casting, retrieving and holding the bottom in a current. Because the compartment 35 is located within the body 20, the carefully designed outer shape does not change with loading and so can be cast in a predictable way which facilitates casting accuracy. It will be appreciated that a swimfeeder which oscillates or behaves erratically on the retrieve can cause variability in the line lay on the reel spool which, thereafter, adversely affects casting accuracy. Since the weights are held in the compartment 35 in a way which inhibits lateral movement, the lateral stability of the swimfeeder during casting assists with casting accuracy. In addition, since the centre of gravity of the swimfeeder remains on the same central longitudinal axis independent of whether a single weight or a combination of 2 or more weights from the set is or are loaded in the compartment 35, consistency in casting is facilitated. It is thought that it is also advantageous to locate the
holes hole 32a is located such that if a weight becomes jammed in position because of groundbait debris or the like, the weight can be dislodged and pushed towards theopen end 22 of the body 20 by inserting an angler's disgorger through thehole 32a.
Claims (11)
- A swimfeeder kit comprising a swimfeeder (10) having an elongate body (20) having an open end (22) and defining a region (20a) for weights and a region (20b) for bait, a cap (26) for closing the open end (22) and a set of weights (40, 42; 50), wherein more than one of the said weights may be loaded, at the selection of the angler, into the weight region (20a) via the open end (22) and occupy the weight region (20a) at the same time, characterised in that the centre of gravity of the weights (40, 42; 50) in the weight region (20a) Is kept on the same longitudinal axis (A-A) of the body (20) independent of the number of weights loaded in the weight region (20a).
